Abstract

OBJECTIVE:To describe a novel surgical technique for the correction of recurrent obstructive urolithiasis in male goats.

STUDY DESIGN:Clinical case series.

ANIMALS:Castrated male goats (n = 4).

METHODS:Medical records of male goats having undergone vesicopreputial anastomosis (VPA) as a treatment for obstructive urolithiasis were reviewed for history, signalment, clinical signs, and intraoperative and postoperative complications. Long-term follow-up (≥12 months) was obtained by telephone interview with owners or by clinical examination.

RESULTS:All goats had undergone at least one surgical procedure (median, 2.5, range 2-4) to correct obstructive urolithiasis before undergoing VPA. Postoperative complications included premature removal of the tube from the bladder (1 goat), bacterial cystitis (2), and abscess formation (1). One goat suffered stricture of the anastomosis site 3 months following the original procedure and underwent a second VPA and 1 goat died 7 months after surgery due to severe, acute hydronephrosis and renal failure. Long-term survival ≥12 months was good with 3/4 goats (75%) or 3/5 VPA procedures (60%) having unobstructed urine flow at 12 months.

CONCLUSION:Vesicopreputial anastomosis is a feasible surgical procedure for the correction of recurrent obstructive urolithiasis in male goats and one that can result in a favorable clinical outcome. Further investigation in a larger population of goats is warranted for the evaluation of the suitability of VPA in male goats with obstructive urolithiasis.

Equine Gunshot Euthanasia: Creation of a 3D-Printed Model with Integrated Sensors for Training.
Here, we report the development and production of a portable, reusable, equine gunshot euthanasia training model. The model facilitates the training of veterinary personnel and first responders in successful gunshot euthanasia, providing instantaneous feedback on the likelihood of a shot causing immediate, humane death in a live animal.

Acute onset of circling and dull mentation in a 1-year-old male neutered domestic shorthair cat.
CNS cuterebriasis represents a neurologic disease more common in cats than dogs, resulting in presentation during summer months with acute onset and often asymmetric, focal or multifocal, intracranial signs preceded by upper respiratory disease.

Neutering is not associated with early-onset urethral obstruction in cats.
Of 84 cats with signs of UO included in this study, 28.6% were classified as intact, 28.6% as prepubertal neutered, and 42.8% as post-pubertal neutered. Intact cats had a significantly earlier onset of UO compared with prepubertal and post-pubertal neutered cats, as seen by the age at obstruction (3.6 vs 5.7 and 5.5 years, respectively).

High-pressure injection of paint into the hand: A small injury with serious consequences.
High-pressure injection injury to the hand is a serious lesion threatening the limb. Several injected materials are involved, and paint is known to have the most serious consequences, with a high amputation rate. Early diagnosis and prompt treatment are two important prognostic factors for a better outcome.

Toxicity of House Plants to Pet Animals.
This review article describes in detail the most common and popular indoor poisonous plants grown in Europe, the mechanisms of action of their active substances and clinical signs of the respective poisonings. This manuscript is supplemented with rich photographic documentation of these plants not found in similar articles, and also includes a description of the treatment of individual types of poisoning.
